The present invention provides a wheel spraying device, comprising a frame, an electric motor, a hollow shaft, a ring flange, and cylinders. During use of the device, the need of jacking up and rotating a wheel in wheel spraying can be met, and the difficulty of removing the protection plugs of bolt hole due to thickening and clogging after completion of spraying can be completely avoided. Meanwhile, the device has the characteristics of simple structure, convenience for use, low manufacturing cost, and safe and stable performance. |

1. A device, comprising a frame (1), an electric motor (2), a rotary joint (3), a synchronous belt (4), a belt pulley I (5), a belt pulley II (6), a lower end cover (7), a bearing seat (8), a hollow shaft (9), a lower piston (10), a guide flat key (11), a piston rod (12), an upper end cover (13), a spring (14), a ring flange (15), an upper piston (16), a cylinder barrel (17), a stop screw (18), jacking posts (19), a central positioning post (20), a stop lever (21) and a bottom plate (22), characterized in that the rotary joint (3) and the belt pulley II (6) are fixed below the lower end cover (7); the electric motor (2), at a shaft end of which is mounted the belt pulley I (5), is fixed at a side surface of the frame (1), and drives the lower end cover (7) and the hollow shaft (9) to rotate by the synchronous belt (4); the hollow shaft (9) is vertically fixed in the bearing seat (8) above the frame (1) by a bearing;
wherein a cylinder I is formed in a manner that an upper end of the piston rod (12) is connected with a lower part of the ring flange (15), and lower end of the piston rod (12) is connected with the lower piston (10), and wherein the lower piston (10) slides up and down without rotation inside the hollow shaft (9) by the guide flat key (11), and wherein the upper end cover (13) is mounted above the hollow shaft (9) for guiding the piston rod (12), and wherein the lower end cover (7) is mounted below the hollow shaft; wherein a cylinder 11 is formed in a manner that the upper piston (16), above which the jacking posts (19) are mounted, is slidable along the inner wall of the cylinder barrel (17) and the outer wall of the lower part of the ring flange (15), and wherein the outer wall of the lower part of the ring flange (15) guides the upper piston (16), and the bottom plate (22) is mounted below the cylinder barrel 17; and wherein the stop lever (21) is fixed above the ring flange (15), and the central positioning post (20) cooperates with the inner wall of the ring flange (15) and floats up and down by the spring (14) below and the stop screw (18). |
